💅 wm8958_mic_detect(9) — like, the kernel API manual bestie 🎀

okay so first things first, the manual name is wm8958_mic_detect(9) and this whole page lives in the Kernel API Manual, which is exactly where you'd expect a kernel API to be, no cap ✨

🌸 NAME 🌸

wm8958_mic_detect — turns on microphone detection via the WM8958 IRQ 🎤✨

---

🦋 SYNOPSIS 🦋

int wm8958_mic_detect (struct snd_soc_component *component , struct
       snd_soc_jack *jack , wm1811_micdet_cb det_cb , void *det_cb_data ,
       wm1811_mic_id_cb id_cb , void *id_cb_data );

like, yes, that's a whole lot of arguments, but we're gonna go through every single one, i promise 🫶

💖 ARGUMENTS 💖

• component — the WM8958 component 🎛️ that's the star of the show
• jack — the jack to report detection events on 🔌 this is where the gossip gets reported
• det_cb — detection callback 👀
• det_cb_data — data for detection callback 📦
• id_cb — mic id callback 🎤
• id_cb_data — data for mic id callback 📦

every arg accounted for, nothing skipped, periodt 💅

✨ DESCRIPTION ✨

so this is the part where it gets good 💖 — wm8958_mic_detect enables microphone detection functionality for the WM8958.

By default, simple detection is what you get, and it supports the detection of up to 6 buttons plus video and microphone functionality. six buttons!! that's so many buttons, honestly iconic 🔥

The WM8958 has an advanced jack detection facility which is able to support complex accessory detection, especially when used in conjunction with external circuitry 🧚 that's the fancy stuff.

And in order to provide maximum flexiblity — yes bestie, the manual literally spells it "flexiblity", we keep it exactly as it is 🙈 — a callback is provided which allows a completely custom detection algorithm 🛠️ like, build your own detection algorithm, main character energy fr fr.
